The Democratic Party of Japan called Monday for a turnaround in Prime Minister Shinzo Abe's economic policies and said the main opposition party will work to narrow disparities in wealth and revive a "wealthy middle class."

In its policy platform for the upcoming election, the largest opposition party attacks "Abenomics" policies as having worsened living conditions.

Instead, the DPJ platform, announced Monday, seeks a "flexible" monetary policy that takes heed of people's lives and promises a growth strategy that will lead to a better future.
